[Heinrich] Schütz's first masterpiece in the "grand Italian manner" was his setting of The Psalms of David in 1619. He is often called the father of German music, and it is refreshing and enlightening to observe that he based his music almost exclusively on Biblical texts....Psalm 121 is an example of a superb union of words and music.
